Enerkey 6s 25.2v 200A Bms Battery Protection Board For 18650 Li-ion Battery Pack Car Start BMS
BMS is a key technology for electric vehicles. The industry is in a rapid development stage:
The battery management system (BMS) mainly plays the role of intelligent management and maintenance of each unit battery, preventing the battery from discharging and overcharging, extending the battery life, and monitoring the battery. There are currently three common BMSs, namely centralized BMS, distributed BMS, and semi-centralized BMS. Each of them has its own advantages and disadvantages and is used in different scenarios. In terms of the application market structure, centralized BMS currently accounts for a higher proportion, reaching more than 55%, because the centralized BMS structure is simpler and the cost is lower. Distributed BMS is highly reproducible and can meet the application needs of different fields, and will become the main development direction of the industry.
BMS is currently mainly used in three major fields: energy storage, new energy vehicles, and consumer electronics. BMS is one of the key technologies for electric vehicles. Its application in the field of new energy vehicles accounts for about 55%, followed by the field of energy storage, accounting for 23%, and the field of consumer electronics accounts for 22%. Due to the rapid development of the new energy vehicle industry in the past five years, the proportion of BMS in new energy vehicle applications has increased significantly, accounting for about 40% in 2016.

Wiring precautions:
1. Installing the protective board requires a certain amount of
technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad
position to the total negative terminal of the battery (the B- wire
should be soldered to a short and thick wire) and solder the wired
terminal to the battery pack first, and then insert the protective
plate.
3. The connection between the battery terminal B- and the
protection board terminal B- should be short and thick, otherwise
it will cause the protection board to charge and discharge in
advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
